AUXITO 912 921 LED Bulbs for Backup Reverse Light Bulbs, 42-SMD 400% Brighter, 6000K White, Non-polarity 906 W16W T15 921 LED Bulb Direct Back Up Parking Light Replacement Lamp, Pack of 2ClimatePartner certified

I installed these LEDs in my 2009 Mercedes CLK 350, and they worked flawlessly right out of the box as reverse lights. If you’ve ever upgraded bulbs on a Mercedes, you know how picky the CANBUS system can be, but these bulbs didn’t trip any errors or warning lights at all.The brightness is a huge improvement over stock, with a clean white light that gives the car a more modern look. Installation was quick and easy, and the build quality of the bulbs feels solid and durable. They've been running for a few weeks now with no flickering, dimming, or heat issues.If you own a CLK or any Mercedes from this era and are worried about compatibility or dashboard errors, don’t be, these bulbs are truly CANBUS-compatible and work perfectly. Highly recommend!

Great buy. Nice and bright. I bought two sets of these as I intended to use them as turn signals and day time running lights. However my 2003 Silverado did not recognize them as having blinker functionality. They blink / pulse, but the truck didn’t like them and acted as if I had a bad bulb (Rapid blink). Going to go ahead and leave 5 stars, however, description should be adjusted. This bulb, at least this color, did not work as a blinker bulb.They work great for day time running lights though and I’ll likely (hopefully) use the second set as reverse lights once my truck is out of the paint booth.

These AUXITO 912/921 LED backup bulbs are a game-changer! The difference between these and the stock halogen bulbs is truly night and day. They claim 400% brighter, and I believe it – the 42-SMD chips put out an incredible amount of clean, 6000K white light. Reversing at night is so much safer now, as my backup camera view is significantly clearer and brighter, illuminating everything behind me perfectly.Installation was incredibly easy. They are non-polarity, so I didn't have to worry about which way they went in, and they fit perfectly as a direct replacement for the old T15/921 bulbs. No flickering, no errors, just instant, brilliant light.If you're looking to seriously upgrade your reverse lights for better visibility and safety, these AUXITO bulbs are an excellent choice. Fantastic brightness, easy installation, and a crisp modern look. Highly recommended!

lights work good not great. They have a very fast blinking speed and the dash display said the bulbs both right and left are burnt out but both work. They are pretty bright though.

I installed them on my 2011 VW GTI MK6 and no dashboard errors. Good price, good quality, easy to install and bright!

Wow these are nice and bright! We installed for daytime running lights. They will see me coming now, no doubt. Definitely recommend.

Great upgrade for a reverse bulb! Quality is top notch works amazing, super bright .

3157 LED bulb size was bright however produced hyper flashing in my 2011 Nissan Frontier. I contacted the seller who then sent me 2 finned 50Ω resistors. I soldered them in parallel to the bulb leads and that helped slow the flashing down to regular frequency.
